module Gtk::FileChooser

Overview

GtkFileChooser is an interface that can be implemented by file selection widgets.

In GTK, the main objects that implement this interface are Gtk#FileChooserWidget and Gtk#FileChooserDialog.

You do not need to write an object that implements the GtkFileChooser interface unless you are trying to adapt an existing file selector to expose a standard programming interface.

GtkFileChooser allows for shortcuts to various places in the filesystem. In the default implementation these are displayed in the left pane. It may be a bit confusing at first that these shortcuts come from various sources and in various flavours, so lets explain the terminology here:

File Names and Encodings

When the user is finished selecting files in a GtkFileChooser, your program can get the selected filenames as GFiles.

Adding options

You can add extra widgets to a file chooser to provide options that are not present in the default design, by using Gtk::FileChooser#add_choice. Each choice has an identifier and a user visible label; additionally, each choice can have multiple options. If a choice has no option, it will be rendered as a check button with the given label; if a choice has options, it will be rendered as a combo box.
